Application filed October 4, 1399. Serial No. 732,445. (No model.)

To ctZZ whom it may concern:

Be it known that we, THOMAS WHITEHORN and HENRY NIoHoLsoN BRADY,subjects of the Queen of Great Britain, and residents of No. 132Flinders Lane, Melbourne, in the Colony of Victoria, Australia, haveinvented certain new and useful Improvements inCigarette-Monthpiece-Making Machines, of which the following is aspecification.

This invention has been devised for the purpose of providing improvedmechanism or apparatus to be used in manufacturing mouthpieces forcigarettes and also for coating such mouthpieces, when being so made,with a covering of paraffin.

In order to make the invention clear, in describing same we will makereference to the accompanying drawings, in whicl1- Figure 1 shows a planof the machine; Fig. 2, a back elevation; Fig. 3, a front elevation.Fig. 4 shows cam for lifting rod carrying paraffin-pad; Fig. 5, a planview showing mandrel in position when mouthpiece is about to be coatedwith paraffin. Fig. 6 is a side view of these with other adjacent partsof the machine. Figs. 7 and 8 show .side and front views, respectively,of modified means of operating gum box containing the adhesiveroller.Fig. 9 shows plan of portion of part shown in Fig. 7.

Upon a central stationary spindle or shaft 1, having bearing in frame10, is mounted a circular plate or disk 2, provided with teeth at itsperiphery, such circular disk 2 being driven by acorrespondiugly-toothed wheel 3, but the teeth of which are interruptedby a plain portion 121 on the periphery. This wheel gears with the disk2 and is set upon a shaft 4, set in suitable bearing-blocks 5 5, Fig. 1,and receives its rotary motion from any convenient source, such as froma pulleywheel set on it or by means of a crank-handle. Upon the tootheddisk 2 and near its circumferential line is arranged a mandrel 6. Themandrel 6 has a tapered shank and is provided with an incut or slit forthe reception of the tongue or lip of. the piece of paper to be twistedinto the mouthpiece. .The mandrel passes through a circular hole formedin the disk 2 and which has flanges 13 14, Fig. 1, encircling it. Theback of the mandrel carries a small toothed pinion-Wheel 7. Locknuts orstops are provided at 8 on the mandrel. The small toothed pinion-wheel 7is arranged to recceive rotary motion from segmental frame 9, which isfixed to the standard 10. The segmental frame 9 has a por-. tion 11 withinternal teeth and a portion 12 with external teeth. The flange 14,Figs. 1 and 5, has a slot in its periphery, and a spring 15, affixed tothe disk 2, bears in the said slot and presses against the mandrel toprevent its turning except under pressure.

17 represents a holder for the paper blanks which are to be made intothe mouthpieces. This holder in plan corresponds in form with the shapeof the paper blanks andis supported by a standard 18. The holder isprovided with a false bottom 100, Fig. 2, which is arranged to moveupwardly during the operation of the machine, so as to maintain thepaper blanks at a constant level. This is effected by means of'ascrew-rod 21, fixed to the false bottom plate and which passes through asleeve 20, attached to the bottom of holder 17. The sleeve supports aratchetwheel 19, which is turned by spring-pawl 22, which is pivoted toan arm 97, Fig. 2, projecting from a sliding frame 23. This slidingframe is of L shape, the horizontal limb 24 of which slides in adovetailed recess formed in a fixed block 25 and has a slot 96, Fig. 3,which encircles shaft 4. A pin or roller 26 is affixed near the end ofthe frame 24 and is arranged to ride upon cam 27, set upon the shaft 4.A spring 101 is affixed at one end to the frame 24 and at the other endto the fixed block 25 and serves to return the L-frame against theaction of the cam 27. The frame 23 has a dovetailed slot, in which avertical plate 29 slides. This plate 29 is bent into suitable form andcarries receptacle 30, which is arranged to hold gum or other suitableadhesive substance. This box is tapered toward its bottom and which isclosed in by a roller 31. This roller is set upon a spindle 32, Fig. 3,having hearings in the sides of the receptaclev 30, and said spindlecarries a small ratchet-wheel 33. A pawl ard 18. wheel, so as to turnthe roller.

. block 25.

is set at the back of the pawl. The front of the receptacle 30 has ahinged plate 115 and a thumb-screw 116 for adjusting the pressure ofsame against roller to regulate the flow of gum. The box 17 aforesaidhas its back plate 36 hinged at the bottom to the box and carries an arm37, Fig. 3, which projects upwardly. The box 30 in its movement(hereinafter described) comes in contact with the said arm 37, so as toturn the back plate on its hinge and so release its pressure from thepaper blanks 102 and make room for the roller. A spiral spring 38 isconnected at one end to the side of box 17 and at the other end to back'plate 36 to return same when pressure is released. Vertical motion isgiven to the plate 29, Fig. 3, and box 30 by means of a rod 39,connected withit (see Fig. 2) and passing down to a rockin g lever,which latter is pivoted at 40 to fixed The rod 39 engages with andslides upon the arm 41 of said lever. The opposite arm 42 terminateswith roller 43, which rides upon a cam 44, set upon the shaft 4.

The toothed wheel 3 aforesaid has an annular rim 46, Fig. 2, upon it,which extends about two-thiids around it and forms with the centralportion 47 a groove 48, the edges of the said rim 46 being tapered off.A roller 49, set at the end of plate 50, is arranged to enter and travelthrough the said groove. This plate 50is pivoted at its bottom to fixedframe 51 and has a spring 52 set beneath it to exert an upward pressure.At the top of the plate 50 a pin 53, Fig. 2, is set and projectsupwardly and is arranged to enter a hole formed in tapered strip 54,(four of which are set upon the disk 2 at its back.) The strips 54, withthe plate 50, serve to lock and hold the disk while the wheel 3 is outof gear with the toothed disk 2. An arm 55, Fig. 2, is pivoted to theframing 10, its other end engaging with cam 56 on shaft 4. A rod 57rests upon the said arm 55. This rod works in fixed guide 58 and carriesbent frame terminating in rack-bar 59. This rack-bar is arranged toengage with pinion 60, having bearing in standard 117. The pinion 60 isintimately connected with toothed segment 61, and which is arranged togear with pinion 7, as hereinafter described. Aspring 103 is provided toreturn the parts after action.

To the front of the disk is secured a block 63, Figs. 1 and 6, whichforms a bearing for a spindle 64, which has at one end spokes or radialarms 66, the other end being provided with a head or block 67, whichlies between the backing plates or arms 68 68, pivoted to the top ofblock 63, Figs. 5 and 6. A portion of the inside faces of these arms iscurved, and they are arranged-When closed to encircle the taperedportion of the mandrel 6. There will be upon the disk 2 a block 63 andconnected parts for each mandrel 6. A plate 70, Fig. 5, is secured tothe side of one of these arms 68 and overlaps the other arm when closedand forms a guide for the paper blank entering the mandrel. Springs 71are arranged to impinge against the backing plates orarms 68. The block67 aforesaid is of more or less elliptical form, so that when thespindle is turned said block will open the arms. Upon the mandrel ismounted a sleeve 72, which has a recess form ed by flanges 73. Thisrecess receives the bifurcated end of a bent arm 74, Figs. 5 and 6. Thisarm is received by and pivoted in a socket-piece 75, which is loose uponthe shaft 1. A hub 76, provided with radial arms 77, is fixed to theshaft 1, and which serves a double purposenamely, to turn the spindle 64as the spokes 65 66 come into contact with it and so open the arms 68and cause the bent arm 74 to turn outwardly upon its pivoted end as thesaid arm rides over the inclined faces of the arms 77. The bent arm willthus move the sleeve forward on its mandrel, the return of same beingprovided for by spring 78, connected at one end to the said sleeve andat the other end to the flange 13.

It is to be understood that the arms 77 are stationary and that theirouter curved ends are in the path described by the spokes 65 66 of thespindle 64 as said spindle is carried around by the disk 2 and that whenone of said spokes is brought in contact with one of the arms 77 itrides over the curved surface of said arm, and therebya partialrevolution is given to the spindle 64 to open the arms 68, ashereinafter set forth.

80 represents a receptacle which holds paraffin. This receptacle issupported by plate 81, secured at the end of shaft 1. A pad 98 is setwithin the box, being supported by an arm 82, projected from sleeve 83,set upon rod 84. A stop-collar is set upon rod 84 beneath the sleeve,and a small spiral spring 86 intervenes between the said sleeve andcollar, the sleeve being held by a nut 122. The rod passes down throughhole in guide-frame at 87. A branch rod 88 projects from said rod 84 andis arranged to ride upon cam 89, Fig. 4, which latter is set upon theshaft 4. The end of the rod 88 is provided with suitable means to enableit to ride upon the cam, such as a bent plate 90. The box 80 is providedwith guide-plates 91 for the arm 82 as it rises with the rod 84.

The shaft 1 is made hollow, Fig. 6, and is provided at its end with aconnection-piece 92, Fig. 1, for gas-tubing, or it maybe connected witha gas-pipe. A bunsen 93, Fig. 6, is connected with hollow shaft 1 andisprovided for the purpose of heating the paraffin in the receptacle 80.

Inthe drawings We have for the sake of clearness shown one mandrel only;but the machine illustrated is adapted to carry and operate four. Thefeeding mechanism also would be in duplicate to feed a mandrel inposition ondisk opposite to that shown, Figs. 1 and 2.

The modus opercmcli of the invention is as follows,(the operation of onemandrel only being described, the others being analogous and synchronousin action Assume the machine to be in position shown on Figs. 1, 2, and3. WVhen in this position, the box 30 will have descended and its gummedroller 31 will have picked up a paper blank, and on the further rotarymotion of the shaft 4 in the direction indicated by arrow, Fig. 2, thebox 30 will be moved forwardas the cam 27 on shaft 4forces out the pin26 on the frame 24. The paper blank will thus be fed to the mandrel 6,the mandrel being in the meantime retained in its position by the pin 53on the plate 50 entering hole in 54 and which prevents the disk fromturning, the gear-wheel 3 meanwhile rotating out of gear. with the disk2. The beveled edge of rim 46 will come in contact with roller 49, sodepressing it and withdrawing the pin 53 from its hole, when the diskwill be free to rotate, and the toothed portion of the wheel 3 willagain meet the teeth of disk 2, and thus cause it to rotate. At the sametime the pinion 7 on the mandrel will meet the teeth of the fixedsegmental frame 11, so causing the mandrel to rotate and to wind thepaper blank upon it into the desired form. The paper which has had itsedge gummed by the roller will be retained in the tubular taperedmouthpiece form. On the further rotation of the disk 2 an arm 66, Fig.6, on the spindle 64 will meet the curved surface of arm 77, so causingthe spindle 64 to turn and the head 67 to open the arms 68. The mandrelwill have now reached a position directly above the pad 98, Fig. 5, andthe next block 54, reaching the pin 53,will now hold the disk with themandrel in this position. The wheel 3 will now be again out of gear withthe disk 2, and on further rotation of the shaft 4 the cam 56 willoperate to raise the bar 55, so as to elevate the rod 57 and cause therack 59 to turn the segment 61 and bring it into gear with the smallpinion 7, so as to turn the mandrel; but 'while this is taking place thecam 89, Fig. 4, will have been turned, so as to raise the rod 84, Fig.3, to cause the paraffin-pad to press upon the mandrel. The paper tubewill thus have its end coated with paraffin. After this operation thewheel 3 will again gear with the disk 2, so as to further turn it and socause the spindle 64, Fig. 6, to be further turned as its arm 66 movesover 77, and the head 67 will turn, so as to allow the arms 68 to movetoward each other. At the same time the bent arm 74 will ride over aninclined face of one of the arms of block 76, so as to move the sleeve72 outwardly and throw off the mouthpiece now finished, and the spring78 will cause the sleeve to be returned to its normal position. The arms68 will close upon the mandrel, which will now have reached a positionto again receive a paper blank from the duplicate feeding mechanism,(not shown,) and the operation of making a mouthpiece will be repeated.

WVe may alternativelyconstruct the gumbox as shown, Figs. 7 and 8, itbeing in this arrangement supported by arms 105, secured upon a verticalspindle 106, having bearing in standard 107. The standard has a slot 108in it, and a pin 109 upon the spindle 106 projects through the saidslot, and is arranged to be operated by cam 110 upon shaft 111, the saidshaft being actuated from any moving part of the machinery convenientfor the purpose. The pin 109 is divided and the divided ends 118 119 arearranged to travel upon the cam, which has two ways, formed one by themain plate 110, the other by plate 120, secured thereto.

In operation, assuming the cam to be inthe position shown, Figs. 7 and9, on rotation of the shaft 111 in direction indicated by arrow, Fig. 7,the cam will be disengaged from 118. A spring set in any convenientposition for the purpose will cause the spindle to turn and pin 109 tomove in slot 113, so as to descend in slot 108, and box 112 will fail topick up a paper blank. The end 119 of the pin 109 will now ride upon thecam and along the plate 120, during which time it will again turn thepin 109 into slot 113, the roller meantime feeding the mandrel with thepaper it has previously picked up. The end 118 will now ride upon plate110, and pin and spindle will again fall and the roller 31 will pick upa fresh sheet.

The slot 108 is extended upwardly and has crossslot 114., the object ofthis extension being that an operator may elevate the box and by turningthe spindle cause the pin 109 to be held in slot 114, during which timehe may refill the boX 17 with paper blanks 102.
